摘要：

Continuous wave proton second moment and line shape studies of the solid state trimethylaluminum dimer, Al2(CH3)6, have shown that all the methyl groups in this compound rotate about their triad axes at 77°K. An activation energy of 840±40 cal/mole was found for this methyl group rotational process from the temperature dependent static and rotating frame spin-lattice relaxation times (T1 and T 1ρ, respectively) studies. These observations tend to support the two-electron three-center Al-C-Al bond model for the bridging methyl group carbons. © 1979 American Institute of Physics.
